UNITED STATES PATENT OFFICE.

WILLIAM H. WOODCOCK, OF BUFFALO, NEW YORK, AS BIGNOR TO NIAGARA FORGED STEEL COMPANY, OF BUFFALO, NEW YORK, A CORPORATION OF NEW YORK.

BRAKE-BEAM.

To all whom it may concern:

Be it known that I, WILLIAM H. W001)- oooK, a subject of the King of England, and resident of Buffalo, in the county of Erie and State of New York, have invented a new and useful Improvement in Brake-Beams, of which the following is a specification.

The object of this invention is the production of a simple brake beam which can be roduoed at comparatively low cost, whic permits of readily and easily attaching the fulcrum and brake heads, and which has .a greater capacity of resisting tgrsional or other destructive strain proportioned to the amount of metal in the beam.

In the acgompanying drawings: Figure 1 is a top plan view of my improved brake beam. Fig. 2 is a front elevation thereof. Fig. 3 is a rear elevation thereof. Fig. 4 is a cross section in line 44, Fig. 2.

Similar letters of reference indicate corresponding parts throughout the several views.

My improved brake beam comprises a vertical web A, a rib B arranged lengthwise on the central art of the front side of the web, and two anges C, C arranged lengthwise at the upper and lower edges of the web and projecting rearwardly therefrom or in a direction opposite to the rib B.

Midway of its length the brake beam is provided with a fulcrum D to which the brake lever is attached. This fulcrum may be of any suitable construction but is preferably constructed of bifurcated form so that it can be secured against opposite sides of the rib.

and engage with the web.

Specification of Letters Patent.

Application filed June 24, 1907.

Patented April 7, 1908.

Serial No. 380,435.

Brake heads E, E are arranged at o posite ends of the brake beam. Each 0 these heads is provided on its rear side with two lugs e, e which are secured to opposite sides of the rib by a bolt f and hear at their rear .ends against the front side of the web.

The brake shoes .may be detachably secured to the brake heads in any suitable or ap roved manner.

t will be noted that a cross section of this brake beam forms four angles at different points producing a structure which is capable of resisting destructive strains in all directions and is superior in strength to other brake beams oontainin an equal amount of metal. Furthermore t is brake beam mits of conveniently attaching thereto other parts of the brake rigging and the same can be rolled as readily as any of the simple forms of flanged iron, thus rendering it possible to produce the same at comparatively low cost.

I claim as my invention:

A brake beam comprising a web, a rib arranged lengthwise on the "central art of one side of the web, flanges arranged iengthwise at opdposite edges of the web and projecting in a irection opposite to the rib, and brake heads each having two lugs which are seagainst said web, substantially as set forth.

Witnesses:

THE L. POPP, ANNA HEIGIS.

Witness my hand this 19th day of June,

cured to opposite sides of said rib and hear"
